Abstract
The utility model provides an anti PID solar energy component of high voltage overlength, includes backplate, toughened glass and EVA, the backplate adopts the rate of permeating water to be less than 1.5 gm2d's backplate, toughened glass adopts super white low indisputable toughened glass, EVA adopts anti PIDEVA, the utility model discloses direct current side input voltage improves the back, and the every string of joinable is the multicompartment more, and the direct current cable use amount of receiving the dc -to -ac converter reduces, and the quantity of flow box dc -to -ac converter of converging also can correspondingly reduce, has reduced the cost in power station, voltage improves the back, and the line loss reduces also lets the output electric quantity increase, effectively reduce the influence of PID phenomenon, avoid the power reduction that the PID phenomenon caused.
Description
Technical field
The present invention relates to a kind of high voltage overlength anti-PID solar components.
Background technology
Domestic photovoltaic owner flows assembly and matching component is all based on the voltage request design of DC terminal 1000V and manufactures, and its cost of electricity-generating and generating efficiency are difficult to meet large-sized photovoltaic power station and the demand of Large Copacity generating equipment.Contrast 1000V, the pressure assembly more than 1500V has the advantage become apparent from.The pressure high-voltage assembly more than 1500V means lower photovoltaic system cost, and after DC side input voltage improves, often string can connect more multicompartment, and the direct current cable usage amount receiving inverter reduces, and the quantity of header box inverter also can reduce accordingly；Meanwhile, after voltage improves, line loss reduces also allows output electricity increase, but in prior art, corresponding measure does not improves pressure.In photovoltaic system, PID phenomenon once occurring, output can be caused to be decreased obviously, generated energy reduces.Anti-PID assembly can reduce the loss that power drop causes.
Summary of the invention
For solving the problem that existing solar components exists, the invention provides a kind of high voltage overlength anti-PID solar components, this assembly can tolerate more than 1500V high voltage, can be tested by 600h PID.
For achieving the above object, the technical solution adopted in the present invention is: a kind of high voltage overlength anti-PID solar components, including backboard, safety glass and EVA, described backboard uses the permeability rate backboard less than 1.5 g/m/d, described safety glass uses ultrawhite low ferrum safety glass, and described EVA uses anti-PIDEVA.
Compared with prior art, the invention has the beneficial effects as follows: after DC side input voltage improves, often string can connect more multicompartment, and the direct current cable usage amount receiving inverter reduces, and the quantity of header box inverter also can reduce accordingly, reduces the cost in power station；After voltage improves, line loss reduces also allows output electricity increase；Effectively reduce the impact of PID phenomenon, it is to avoid the power drop that PID phenomenon causes.
Accompanying drawing explanation
For this utility model is described further, the drawings and specific embodiments are set forth below.
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
As it is shown in figure 1, low for ultrawhite ferrum safety glass 1, anti-PID EVA2, ozone process anti-PID cell piece 3, anti-PID EVA4, backboard 5 are then laminated according to order stacking as shown in the figure；Its dorsulum 5 permeability rate is less than 1.5 g/m/d, can tolerate the high voltage more than 1500V；Aluminum frame is installed on laminate four limit, and the shady face at backboard installs 7 rosettees.
It is clear that above-mentioned embodiment is only one of them embodiment of the present utility model, any simple modifications on present configuration or principle belongs to protection domain of the present utility model.
